Chapter 2 Basic MSFC Software Configuration

Performing Other Configuration Tasks

If you set the boot field value to 0, you must boot the system manually by entering the boot command at the ROM monitor prompt (rommon>).

If you set the boot field value to 0x2 through 0xF and a valid boot system command is stored in the configuration file, the system boots the Cisco IOS software image as directed by that value. If no boot system command is present in the configuration file, the system computes a default boot filename for booting from a network TFTP server.

In the following example, the software configuration register has been set to boot the system from the Flash memory SIMM and to ignore the Break function at the next reboot of the router:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# config-register 0x0102

Router(config)# boot system flash [filename]

Crtl-z

Router#

With the configuration register set to “0x0102,” the system creates a default boot filename. In forming this filename, the system starts with the name cisco and appends the octal equivalent of the boot field number, a hyphen, and the processor type.

Recovering a Lost Password

This section tells you how to recover a lost password.

 

 

Note

If the enable password is encrypted, the following procedure will not work for

 

 

 

password recovery and you will have to reconfigure the system before

 

 

 

attempting a reboot. To reconfigure the system, use the displayed

 

 

 

configuration obtained by entering the show startup-configcommand in the

 

 

 

privileged EXEC mode.

 

 

 

 

 

 

 

 

To recover a lost password, perform these steps:

 

 

 

 

 

 

Step 1

Attach an ASCII terminal to the console port.

 

 

Step 2

Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 2 stop

 

 

 

bits (or to whatever settings the console port is currently set).
